I really wish the US would do something about the dying mall spaces. In the failing commercial real estate market they are just being left to rot away.

Turn them into small communities. Build housing within or above the mall space, develop the space into a walkable city of sorts. One of the things preventing comfortable walkable neighborhoods in my area is the 6 months of winter. Creating that with the indoor mall, similar to the intent of the mall, would really make them useful.

That or just waste 100,000 sq ft of covered and climate controlled space while the housing market continues to skyrocket. Every new apartment being build around me, and seemingly everywhere, are that 5 on 1 design. Retail spaces on the first floor, apartments above. A dying mall lends itself to that style of living with an opportunity to create a really large and vibrant indoor park space.
